I'm guessing it's a matter of degree of volatiles volume changes the level of risk.Getting a fire really hot before adding more coal is exactly what some anthracite users have learned works best to get a faster recovery. So, is it quicker recovery ? Or ....QUICK, take cover.
I just noticed this.
No, it's not Quick, take cover. It's that the burn characteristics are different between the two coals, so they must be treated a little differently. Anthracite is a very hard coal, slower to light, with less volatiles. Bituminous is a soft coal, faster to light, with more volatiles. This is why you don't want (or need) a really hot bed of coals when using Bit.
Even with Anthracite, I've noticed you guys telling others to let a small spot burning when adding coal, so as to avoid a puffback. It is the same with Bituminous coal, and I'll even say it may be more critical that this advice be followed.
I hope this made sense.
